So in this issue we get straight up told that Nightcrawler is in a new dimension and that means the sorcerer's statement of "not going to tell you" regarding how he can teleport either means the writer has no xplanation.
And if the writing wasn't lazy enough already, a giant Storm-look-alike came in to change everything up. Which makes it all the more baffling how Kurt figured out that the magical power was still in the staff despite the sorcerer's words. That is surprisingly smart for this comic.
Of course this was only temporary as when Kurt was teleported throughout one dimension after the other, he ends up with a tv-set with an old lady inside it and she tells him everything and explains… an apparently all Nightcrawler had to do was to really want to be home.
